I think that would be OK. While it's a bad idea to
randomly make
adjustments, you are not doing that. You have a fairly clear idea of
what's going on, and what that trimmer adjusts.
As soon as I touched the trimmer, I discover the problem !! The cursor was
instable !!
The outputs voltages changes only posing the screwdriver on the trimmer.
Now, with a new trimmer (a good Beckman) the voltage in full adjustable in
the range.
I have tested this power supply with various load and the regulation on 5V
and 12V is good.
I'm writing a web page with all your notes, my experience, photo, schematic
and data sheets.
Thanks a lot !
